LUBRIGATOR.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed February 26, 1906. Serial No. 302,839.

for its object to provide a simple, durable and efficient structuralformation and combination of parts whereby a positive and multiple feedof the lubricant is attained without the use of inlet and outlet checkvalves, and with 5 which the amount of lubricant fed by each individualdelivery can be independently adjusted or regulated as required, all aswill hereinafter more fully appear.

In the accompanying drawings illustrative of the present invention :Figure 1 is alongitudinal vertical sectional elevation on line av-a 3.Fig. 2- is a detail horizontal section on line 55-50, Figs. 1 and 3.Fig. 3 is a transverse vertical section on line E fU Fig. 1. 4c is anend elevation of the operating cam. Fig. 5 is a detail plan of same,showing the arrangement of the 1nclmed pro ect1ons by wh1ch the slldingvalve of the series of pumps is intermittently re- 20 ciprocated.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings :1 is the bottom plate or base of theapparatus provided with a longitudinal row of pump cylinders or chambers2, the inclosing walls of which in the preferred construction of thepresent invention, as shown in Fig. 3, form an integral part of the base1, with the inlet-outlet so ports 3, arranged transversely in said base.

a is a longitudinal channel formed in the base 1 and having opposedwalls which con stitute the seat for the single controlling slide valvehereinafter described; through the inner of said walls the aforesaidinletoutlet ports 3 open, while tirough the outer of said walls a seriesof outlet ports or passages o, open, and are connected by suitable pipeconnections 6, with the respective bear- 5'0 ings or parts to belubricated.

7 is acasing or housing secured near the margin of the base i andadapted to inclose pump mechanisms, and contain a supply of thelubricant to be pumped, as usual in the present type of apparatus.

8 is an upwardly extending frame fixed on the base 1, for the support ofthe pump operating mechanism hereinafter set forth.

9 is the controlling slide valve above referred to having slidingcontact with the aforesaid exposed walls of the longitudinal channel 4E,and receiving intermittent reciprocation by mechanism hereinafterdescribed; such valve is formed with a series of ports or passages 10extending transversely through the valve as shown in Fig. 2, and whichin one position of the valve are adapted to register the inlet-outletports 3, of the pump chambers with the before described outlet passages5 in the base 1; such valve is also formed with a series of angularpassages 11 extending from the top of the valve to the inner side of thesame, as shown in Fig. 3, and while in the other position of the valvethese angular passages are adapted to register the inlet-outlet ports 3,of the pump chambers with the interior of the housing 7 and the supplyof lubricant contained therein. In the present improvement the saidpassages 10 and 11 are arranged in alternate relation to each other asshown in Figs. 1 and 2, and the arrangement is such that in one positionof said valve, the pump chambers will be in communication with theinterior of the housing to take a supply of the lubricant, and in theother position of the valve communication between the pump chamber andthe tank will be closed, and communication opened between the pumpchambers and the series of outlet passages 5 having connection with thebearings to be lubricated.

12 are springs tending to hold the valve 9 to its seat in the channel 4-while permitting a free longitudinal reciprocation of the valve. Saidsprings are arranged between opposed studs on the valve and a stationarypart of the pump mechanism, as illustrated in Fig. 1.

13 are the series of pump pistons or plungers moving in the row of pumpchambers 2, aforesaid, with their upper ends connected to the series ofopen frontyokes 1a, which span the operating cam shaft hereinafterdescribed.

15 are a vertical series of tubular guide stems at the tops of the yokes14:, in vertical alinement with the pump 13,preferably, and moving in alongitudinal guide bar 16, on the frame 8, aforesaid.

17 are aseries of springs surrounding the guide stems 15, and arrangedbetween the guide bar 16, and the tops of the yokes 14 with a normaltendency to forcibly depress said yokes and the pump plungers 13 car.-ried thereby.

18 area series of vertically adjustable of the adjustable screws 18, tohave bearing,

contact on the lifting cams hereinafter described. With such'arrangementthe direct wear'is upon saidbars so that when'much worn they can bereadily and economically replaced. r

21 is a longitudinally extending cam shaft journaled in the frame 8,aforesaid; such cam shaft is commonto the series of yokes 14, and theirindividual accessories, and in the preferred form of the presentinvention such cam shaft is formed with a series of steps 22 in its camportion, as shown in Figs. 1 and 4, so-that the down or active stroke ofthe series of pump plungers will take place serially, the one followingthe other in short succession, and the whole taking place in a smallpart of one rotation of the cam shaft.

23; is a disk or rim rotating in unison with the cam. shaft 21, and.preferably carried thereon; such disk is provided with a pair ofinclines or cams 24', 25, arranged in diametric relation and projectinglongitudinally from-opposite sides of such disks as illustrated in Figs.1, 2 and 5.

2.6 is a vertical lever pivoted to a fixed part of the machine, with itslower arm in operative engagement with the slide valve 9, while itsupper end is forked to straddle the disk 23 ,to be intermittently movedin one direction by the cam 0r incline 24c, and in the otherdirection-by the cam or incline 25, during a continued operation of theapparatus.

Any ordinary or usual operating mechanism may be employed to impart aslow rotation to the cam shaft 21, without departing from, the spirit ofthe present invention; the mechanism. shown inrthe drawings conslsts inan arrangement of parts as follows-:

27 is a. wormw-heel carried by the cam shaft and. preferably formedbythe-provision of a series ofworm teeth-in the periphery of the disk orrim 23; aforesaid. 28 is" a vertical shaft carrying an endless screw-orworm 29- pump chambers filled with the lubricant,

which mesheswithand drives the aforesaid worm wheel 27. 30 is a wormwheel on the upper end of thevertical shaft 28; and 31 is an endlessworm or screw on a horizontal shaft32, meshing with-and driving the saidworm wheel 30; the shaft 32 in turn receiving motion from a convenientpower source.

The operation of the apparatus is as follows :VVith the series of pumpplungers in their depressed position, as shown in the drawings, and withthe valve 9 in a position.

to register the pump chambers with the interior of the housing 7,andwith a continued rotation of the cam shaft. 21, the series of yokesand their connections are gradually lifted by the cam formation intotheir fully raised position, previousto which the incline 25 movesagainst the lever 26 to shift the valve 9 longitudinally to close thecommunication between the pump chambers and the interior of the housing7, and open communication between the pump chambers and the outletpassages 5. With the series of yokes, etc., fully raised and the the camprojections of the cam shaft, move 7 from under the yokes, and the sameare forcibly depressed by the springs 17'to discharge the lubricant fromthe pump chambers through the outlet passages 5, and to the points, ofuse. A continued rotation'of the cam shaft'shifts the valve 9 back toits original position through the instrumens tality of the incline 24,to begin again a' fresh cycle of the operations just described.
